Custom Field with ReactNative

help
1

Hello there, how can I subscribe to a custom user field ?

Here is the JSON format for Meteor.users collection in the DB

{
    "_id" : "pziqjwGCd2QnNWJjX",
    "createdAt" : ISODate("2017-12-21T22:06:41.930Z"),
    "emails" : [ 
        {
            "address" : "email@email.com",
            "verified" : false
        }
    ]
    "votes" : {
        "laws" : [ 
            {
                "ZyYZ4LDTaeWNMN9eE" : "oui"
            }
        ]
    }
}

PUBLICATION

Meteor.publish("UserVotes", () => {
if (!this.userId) return null;
  return Meteor.users.find(this.userId, { fields: [votes] });
});

SUBSCRIPTION

export default createContainer(params => {
  Meteor.subscribe("UserVotes");
  return Meteor.users.find(this.userId, {
    fields: {
      votes: 1
    }
  });
}, UserVotes);

It returns users.find is not an object, any idea?

Your publication is passing an array with a single element of undefined to the fields key. The fields key should be defined just like you have it in your createContainer code.

You will have to use this format in React Native.

Meteor.collection('users').find({ _id: params.userId });

Hi there, the problem is that you use this in arrow function, the publish function should be written like this:

Meteor.publish("UserVotes", function () {
  if (!this.userId) return null;
  return Meteor.users.find(this.userId, { fields: [votes] });
});

Good catch on that, I didn’t even pay attention to the function type :slight_smile:
